Feb. 22: After falling out of favor in Tampa, Dickerson landed in Pittsburgh, where he'll take over as the primary left fielder (at least against right-handed pitchers). It's no worse a hitters' environment for him than in Tampa Bay's Tropicana Field, and while his OPS declined in every month last year, Dickerson could yet provide some cheap power to deep-mixed and NL-only teams.

Feb. 20: Souza's acquisition provides the Diamondbacks some much-needed power after J.D. Martinez departed via free agency, though Souza shouldn't match Martinez's home-run output, especially not with a humidor being introduced this season. Drury should play regularly for the Yankees while enjoying a similarly favorable hitting environment. Solak, meanwhile, could be a dark horse contender for the Rays' second-base gig at some point this season.

Feb. 17:Shohei Ohtani's arrival in L.A. practically guaranteed a part-time role for Cron, as Albert Pujols will need to shift to first base more often to accommodate Ohtani at DH. In Tampa, Cron has a much clearer path to everyday at-bats at first base, though he's moving to an even worse park for power. He's a low-end mixed league corner infielder.

Feb. 17: Odorizzi gives the Twins a much-needed middle-of-their-rotation arm, though the move from pitching-friendly Tropicana Field for more-neutral Target Field does lower his matchups appeal slightly. He'll be a back-of-your-staff pick at most in mixed leagues.

Jan. 29: No one here is a fantasy standout, but Moss has some power to help in the AL-only endgame, while Buchter could be a ratio/holds helper in the same. Hahn is a pitcher to watch during the spring, if he can land a rotation spot.

Jan. 25: Yelich gets a huge upgrade in home ballparks, but he needs to show continued growth with his launch angle to capitalize. He's more intriguing, but don't get carried away with your home-run expectations. Brinson benefits the most in terms of playing time, on a Marlins team that can afford to be patient through his struggles, giving him the at-bats required to fill the homer and stolen-base categories.

Jan. 19: Freed from the cluttered St. Louis outfield, Grichuk could thrive in a far more homer-friendly environment at Toronto's Rogers Centre. He'll play regularly in right field and despite some questions about his hit tool, could provide 30-plus homers at a discount price.

Jan. 15: McCutchen goes from one pitching-friendly environment to another, and a more extreme one at that, and he'll man the most spacious right field in all of baseball at AT&T Park. His fantasy value shouldn't change much, but he could lose a few home runs. Read more from Eric Karabell.

Jan. 13: You might think of Minute Maid Park as a significantly more hitter-friendly environment for Cole than PNC Park, but that's only true in terms of home runs. It's actually a pitching-friendly environment and boosts strikeouts, and the change of scenery should help, keeping Cole among the top 25 fantasy starters. Musgrove could get a look in the Pirates' rotation, Moran could take over at third base and Feliz provides bullpen depth. All could be endgame targets in NL-only leagues. Read more from Eric Karabell.

Jan. 6: Solarte, who has decreased his ground-ball rate in each of his four years in the majors, moves to a much more homer-friendly environment in Toronto. He's a multi-position infielder who is a nice mid-round pick for an AL-only team.

Jan. 4: Soria is the notable name here, mainly because he lands with a team with little competition for saves. He's a worthwhile AL-only option for those looking to fill the category on the cheap. Alexander could help NL-only owners keep their ERA/WHIP in check.

Dec. 20: Longoria trades one extreme pitchers' park for another, keeping him more mixed-league corner infield material, but he gives the Giants a strong defensive left side of the infield. It's good news for their pitchers. Read more from Eric Karabell.

Dec. 16: A deal driven by cash -- it solved both teams' long-term financial goals -- Kazmir and McCarthy could be useful rotation stopgaps for the Braves. Kemp might not even remain in L.A., while Gonzalez was immediately designated for assignment.

Dec. 15: Galvis should remain a starter in San Diego and maintain NL-only middle-infield value, but this deal was about clearing shortstop for J.P. Crawford in Philadelphia. Crawford is the better fantasy pick thanks to his speed.

Dec. 14: Ozuna, who was likely due some regression anyway, is about as valuable in fantasy in St. Louis as he was in Miami. The ballpark factors are similar for righty power and the Cardinals (4.7) scored almost the same rate of runs per game in 2017 as the Marlins (4.8). Alcantara is a prospect to watch in Miami, where he's more likely to make the team out of spring training. Read more from Tristan H. Cockcroft.

Dec. 14: With Marcell Ozuna headed to St. Louis, Piscotty moves to a team with more opportunity for him to play every day. He's a rebound candidate playing closer to home, though he could lose some at-bats against righties on an Oakland team that likes to platoon. Read more from Tristan H. Cockcroft.

Dec. 12: Headley, acquired in a clear salary dump, could again be on the move, but he's an "only"-league option wherever he winds up. Mitchell's spring warrants a look, as in the right role he could be an NL-only sleeper.
